FIRE RESISTANT INTRODUCTION November 22, 2000 Underwriters
Laboratories in Northbrook, Illinios conducted a one hour fire endurance
and hose stream test on FBH Glass.
Fire Test of window assemblies-UL9:
Test assembly (52"x101") consisting of 1/8" aluminum, steel and
9/16" thick FBH glass.
endurance test: (1 hour duration to 1700° Fahrenheit).
A standard time temperature curve for control of test was utilized.
Thermo couplers and radiometers measured test heat exposure.
stream test: Immediately following the fire endurance
test the fire exposed side of the assembly was subjected to the
impact, erosion, and cooling effects of the hose stream. The hose
stream was delivered through a 2 1/2" hose discharging through a
national standard clay pipe of corresponding size equipped with
a 1 1/8" discharge tip of the standard taper smooth bore pattern.
The distance from the test assembly was twenty feet.
FBH assembly is certified as compliant by Underwriter Laboratories.
